Integrated house decoration gypsum board and integrated preparation process thereof

Abstract

This application discloses an integrated home decoration gypsum board, comprising, from bottom to top, a first basalt fiber felt, a first dense fiber bundle pre-layer, a core layer, a second dense fiber bundle pre-layer, a second basalt fiber felt, and a porous sound-absorbing layer. The core layer comprises a gypsum matrix, and dispersed in the gypsum matrix are an intumescent flame retardant, a nano-silane waterproofing agent, TiO2-loaded activated carbon composite particles, lightweight high-strength aggregate, and lignin fibers. The particle size of the TiO2-loaded activated carbon composite particles matches the particle size of the gypsum particles constituting the gypsum matrix to form a dense filler. This invention optimizes the addition order by first adding the intumescent flame retardant and nano-silane waterproofing agent, followed by the TiO2-loaded activated carbon composite particles. This avoids the waterproofing agent clogging the pores of the activated carbon and the flame retardant eroding the fiber felt, eliminating performance interference between components.

Description

Technical Field

[0001] This application relates to the field of building decoration materials technology, and in particular to integrated home decoration gypsum board and integrated home decoration gypsum board preparation process. Background Technology

[0002] Gypsum board is a core functional material for interior decoration. Its properties such as water resistance, fire resistance, impact resistance, nail holding ability, formaldehyde purification, sound insulation, crack resistance, and sinking resistance directly determine the safety and comfort of the living environment.

[0003] To enhance the multifunctional properties of gypsum board, existing technologies generally adopt the technical route of directly mixing single functional components into gypsum slurry to prepare multifunctional gypsum board.

[0004] However, the direct mixing of the various functional components faces the following technical bottlenecks: The problem of performance interference between components is prominent: the surface coating effect of liquid waterproofing agent can block the pores of activated carbon and weaken the formaldehyde decomposition efficiency; the acidic components of intumescent flame retardant may erode the interfacial bonding of fiber felt and reduce the impact resistance. Synergistic failure is difficult to avoid: The chemical properties and physical forms of each functional component are significantly different, and they are prone to mutual reaction or physical agglomeration during the slurry mixing stage, which leads to the deterioration of various properties of the board and makes it difficult to achieve multi-functional and efficient synergy, that is, the technical problem of "1+1<2" occurs.

[0005] In summary, existing direct mixing technology for single functional components cannot simultaneously achieve the requirements of "functional integrity, synergistic performance, and structural stability," making it difficult to balance the various properties of gypsum board and limiting its application in high-quality home decoration scenarios. Therefore, developing a gypsum board preparation technology that can eliminate performance interference between components and achieve synergistic multi-functionality is the key to improving the overall performance of integrated home decoration gypsum board. Summary of the Invention

[0006] To address the aforementioned technical issues, this application provides integrated home decoration gypsum board and its integrated manufacturing process.

[0007] Integrated home decoration gypsum board includes, from bottom to top, a first basalt fiber felt, a first dense fiber bundle preset layer, a core layer, a second dense fiber bundle preset layer, a second basalt fiber felt, and a porous sound-absorbing layer. The core layer comprises a gypsum matrix, and an intumescent flame retardant, a nano-silane waterproofing agent, TiO2-loaded activated carbon composite particles, lightweight high-strength aggregate, and lignin fiber dispersed in the gypsum matrix. The particle size of the TiO2-loaded activated carbon composite particles is matched with the particle size of the gypsum particles constituting the gypsum matrix to form a dense filler. The first basalt fiber felt, the first encrypted fiber bundle preset layer, the core layer, the second encrypted fiber bundle preset layer, and the second basalt fiber felt constitute a symmetrical layered structure, and the porous sound-absorbing layer is directly bonded to the upper surface of the second basalt fiber felt.

[0008] By adding intumescent flame retardants and nano-silane waterproofing agents to the gypsum slurry in a specific order, they can preferentially bond with the gypsum matrix. This prevents the subsequently added TiO2-loaded activated carbon composite particles from being coated by the waterproofing agent and becoming ineffective. At the same time, the flame retardant is anchored in the matrix and will not corrode the fiber felt. This eliminates the chemical and physical interference between components from the root, providing structural protection for the synergistic realization of multiple functions.

[0009] Eliminating component interference: The flame retardant and waterproofing agent added first are uniformly anchored in the gypsum matrix, while the activated carbon composite particles added later maintain the complete porous structure and photocatalytic activity, ensuring that the function of efficiently decomposing formaldehyde is not affected. Avoid interfacial erosion: The flame retardant is pre-dispersed in the matrix and does not come into direct contact with the basalt fiber felt, thus eliminating the erosion of the fiber felt interface by acidic components and ensuring impact resistance.

[0010] A specific layered structure (basalt fiber felt - pre-set layer of dense fiber bundles - core layer - pre-set layer of dense fiber bundles - basalt fiber felt): This structure achieves structural reinforcement and functional zoning, ensuring the mechanical properties of the board. The first and second basalt fiber felts are symmetrically arranged on both sides of the core layer. The first and second pre-set layers of dense fiber bundles are located between the core layer and the two basalt fiber felts on both sides, forming a symmetrical layered structure of "felt-bundle-core-bundle-felt," which has the following key functions: The functional zones are clearly defined: the basalt fiber felt on both sides provides high impact resistance, the pre-layer of dense fiber bundles provides high nail holding power, the core layer provides water resistance, fire resistance, formaldehyde purification, crack prevention, and sinking prevention, and the porous sound-absorbing layer provides high sound insulation. The layered structure allows each function to work together efficiently without interference. Strong interface bonding: Each layer is tightly bonded to prevent interlayer peeling and structural failure caused by interface separation during use. Symmetrical and stable structure: The symmetrical "felt-bundle-core-bundle-felt" structure ensures uniform stress distribution when the board is under stress, avoids warping and deformation, and further improves the board's impact resistance and nail holding performance.

[0011] Densely Filled Core Structure (Matching Particle Sizes of Activated Carbon Composite Particles and Gypsum Particles): In the core layer, which achieves synergistic anti-sagging and formaldehyde purification functions, the particle size of the TiO2-loaded activated carbon composite particles matches that of the gypsum particles, forming a densely filled structure. This structure offers the following technical advantages: Filler reinforcement: Activated carbon composite particles with matching particle size can effectively fill the gaps between gypsum particles, improve the density and compressive strength of the core layer, and achieve high anti-sinking performance; Full functional retention: While the activated carbon composite particles are densely packed, their porous structure is not coated with waterproofing agent, thus fully retaining the photocatalytic activity of TiO2 and ensuring the realization of efficient formaldehyde decomposition.

[0012] Through the synergistic effect of the above structures, the core performance of gypsum board is finally achieved: "high water resistance, high fire resistance, high impact resistance, high nail holding power, high formaldehyde decomposition, high sound insulation, high crack resistance, and high sagging resistance", which completely solves the pain points of performance interference between components and functional synergy failure in existing technologies.

[0013] The integrated manufacturing process for gypsum board for home decoration includes the following steps: S1: Add the intumescent flame retardant and nano-silane waterproofing agent to the gypsum slurry and stir evenly to obtain the first mixture; S2: Add TiO2-loaded activated carbon composite particles, lightweight high-strength aggregate and lignin fiber to the first mixture, stir evenly to obtain a second mixture; wherein, the particle size of the TiO2-loaded activated carbon composite particles matches the particle size of gypsum particles to form a dense filler. S3: Lay the first basalt fiber felt and the first dense fiber bundle preset layer in sequence in the mold, lay the second mixture on the first dense fiber bundle preset layer, and then lay the second dense fiber bundle preset layer and the second basalt fiber felt in sequence on the second mixture to form a slab; S4: A porous sound-absorbing layer is formed on the upper surface of the second basalt fiber felt, and after curing and drying, the integrated home decoration gypsum board is obtained.

[0014] As a preferred embodiment of the above technical solution, the first and second encrypted fiber bundle preset layers are each composed of multiple continuous fiber bundles arranged at intervals in the same direction, and the extension direction of the fiber bundles is consistent with the length direction of the slab.

[0015] The structure of the pre-defined layer of densified fiber bundles is defined. The continuous fiber bundles are spaced apart along the length direction, which can provide directional reinforcement when the board is subjected to nail holding force. As the main load-bearing unit of nail holding force, the fiber bundles are arranged along the length direction to maximize the nail holding force and avoid board cracking caused by nailing. At the same time, the spaced arrangement can ensure that the slurry penetrates and fills the gaps between the fiber bundles, so that the layers are tightly bonded and prevent interlayer separation.

[0016] As a preferred embodiment of the above technical solution, the porous sound-absorbing layer is a porous structure layer formed by foaming with a pore-forming agent, and the porous sound-absorbing layer is directly bonded to the upper surface of the second basalt fiber felt.

[0017] The molding method and bonding relationship of the porous sound-absorbing layer are clearly defined. The porous structure formed by the foaming of the pore-forming agent can effectively dissipate sound energy and achieve high sound insulation function. The direct bonding between the porous sound-absorbing layer and the second basalt fiber felt can ensure the integrity of the sound-absorbing layer and the board, and prevent the sound-absorbing layer from falling off during use.

[0018] As a preferred embodiment of the above technical solution, the particle size of the TiO2-loaded activated carbon composite particles is smaller than the particle size of the lightweight high-strength aggregate.

[0019] By limiting the particle size relationship between the two types of particles, the activated carbon composite particles have a smaller particle size, which can fill the gaps between the lightweight high-strength aggregate and the gypsum particles, achieving multi-level dense filling and further improving the core layer density and anti-sinking performance; the lightweight high-strength aggregate particles have a larger particle size, which can reduce the overall density of the board and provide skeletal support.

[0020] In summary, the present invention has at least one of the following beneficial technical effects: By optimizing the addition order of intumescent flame retardant and nano-silane waterproofing agent first, followed by TiO2-loaded activated carbon composite particles, the blockage of activated carbon pores by the waterproofing agent and the erosion of fiber felt by the flame retardant were avoided, and the performance interference between components was eliminated. The symmetrical layered structure consisting of a first basalt fiber felt, a first dense fiber bundle pre-set layer, a core layer, a second dense fiber bundle pre-set layer, and a second basalt fiber felt achieves a synergistic improvement in high impact resistance and high nail holding power. By matching the particle size of activated carbon composite particles and gypsum particles, a dense core filling structure is formed, which simultaneously achieves the functions of high anti-sinking and efficient formaldehyde decomposition. Through the synergistic effect of the layered structure and the dense core filling structure, gypsum board simultaneously possesses eight functions: high water resistance, high fire resistance, high impact resistance, high nail holding power, efficient formaldehyde decomposition, high sound insulation, high crack resistance, and high sag resistance. Moreover, each function does not interfere with the others and works synergistically to enhance each other's effectiveness. Attached Figure Description

[0023] The present application will be further described in detail below with reference to the embodiments.

[0024] This application relates to integrated home decoration gypsum board, comprising, from bottom to top, a first basalt fiber felt 21, a first dense fiber bundle pre-layer 31, a core layer 10, a second dense fiber bundle pre-layer 32, a second basalt fiber felt 22, and a porous sound-absorbing layer 40, stacked sequentially. The core layer 10 comprises a gypsum matrix, and dispersed in the gypsum matrix are an intumescent flame retardant, a nano-silane waterproofing agent, TiO2-loaded activated carbon composite particles, lightweight high-strength aggregate, and lignin fiber, wherein the particle size of the TiO2-loaded activated carbon composite particles is specified. The particle size of the gypsum particles that make up the gypsum matrix is ​​matched to form a dense filler; the first dense fiber bundle preset layer 31 and the second dense fiber bundle preset layer 32 are respectively composed of multiple continuous fiber bundles arranged at intervals in the same direction, and the extension direction of the fiber bundles is consistent with the length direction of the slab; the porous sound-absorbing layer 40 is a porous structure layer formed by foaming with a pore-forming agent, and the porous sound-absorbing layer 40 is directly bonded to the upper surface of the second basalt fiber felt 22; the particle size of the activated carbon composite particles loaded with TiO2 is smaller than the particle size of the lightweight high-strength aggregate.

[0025] By pre-adding intumescent flame retardant and nano-silane waterproofing agent to the gypsum slurry in a specific order, they preferentially bond with the gypsum matrix, preventing the subsequently added activated carbon composite particles from being coated by the waterproofing agent. Simultaneously, the flame retardant is anchored in the matrix and will not corrode the fiber felt, eliminating chemical and physical interference between components at the source. Its working principle is as follows: Addition order optimization and component interference elimination mechanism In step S1, an intumescent flame retardant and a nano-silane waterproofing agent are added first. In step S2, TiO2-loaded activated carbon composite particles, lightweight high-strength aggregate, and lignin fiber are added. This stepwise addition achieves spatial isolation and elimination of interference between functional components. Preferred anchoring: Intumescent flame retardant and nano silane waterproofing agent are uniformly dispersed in gypsum slurry in step S1. The flame retardant forms a uniform physical anchor with the gypsum matrix, and the waterproofing agent forms a silane film layer on the surface of gypsum particles. Both preferentially occupy the matrix bonding sites. Functional protection: The activated carbon composite particles added in step S2 are dispersed in the formed waterproof-flame retardant matrix slurry. Their porous structure and TiO2 active sites are not coated by the waterproofing agent due to the subsequent addition, thus maintaining the complete formaldehyde adsorption and photocatalytic functions. Interface isolation: The flame retardant has been anchored in the gypsum matrix and has no direct contact with the subsequently laid basalt fiber felt, eliminating the erosion of the fiber felt interface by acidic components.

[0026] Layered structure synergistic enhancement mechanism The symmetrical layered structure of "felt-bundle-core-bundle-felt" achieves a simultaneous improvement in high impact resistance and high nail-holding power through functional zoning and coordinated force distribution. Impact resistance synergy: The first basalt fiber felt 21 and the second basalt fiber felt 22, which are symmetrically arranged on the top and bottom, serve as impact resistance functional layers. When the board is subjected to external impact, the fiber felts on both sides jointly bear the impact energy. The energy is dissipated through the stretching and breaking of the fibers. The symmetrical arrangement makes the impact resistance of both sides of the board balanced. Enhanced nail holding force: The first and second densified fiber bundle preset layers 31 and 32 are located between the core layer 10 and the basalt fiber felt on both sides, respectively. The fiber bundles are arranged along the length direction. When the screw is driven into the board, the fiber bundles provide directional pull-out resistance. The symmetrical double-layer densified fiber bundles make the nail holding force on both sides of the board uniform and significantly improved. Stable structure: The layers are tightly bonded together. The slurry penetrates the gaps between fiber bundles and the pores of fiber felt during installation. After curing and hardening, it forms an integral structure, avoiding interlayer delamination.

[0027] Core layer dense filling and functional synergy mechanism In the core layer 10, the activated carbon composite particles and gypsum particles are matched in size to form a dense filling structure, simultaneously achieving the functions of preventing sagging and purifying formaldehyde. Dense filling: The particle size of activated carbon composite particles matches that of gypsum particles, which can effectively fill the gaps between gypsum particles. Combined with the skeleton support of lightweight and high-strength aggregate and the crack prevention effect of lignin fibers, the density and compressive strength of the core layer are improved. Synergistic Function: Dense filling does not damage the pore structure of activated carbon composite particles, and TiO2 continuously decomposes formaldehyde under light conditions, achieving synergistic effect of structural enhancement and functional preservation.

[0028] In summary, the integrated home decoration gypsum board of this application achieves a reasonable spatial distribution and non-interference in function of each functional component through the synergistic effect of "optimized addition order - layered structure - dense filling", ultimately obtaining an integrated home decoration gypsum board with eight high performance features, providing core technical support for high-quality home decoration materials.

[0029] The integrated manufacturing process for gypsum board for home decoration includes the following steps: S1: Add the intumescent flame retardant and nano-silane waterproofing agent to the gypsum slurry and stir evenly to obtain the first mixture; S2: Add TiO2-loaded activated carbon composite particles, lightweight high-strength aggregate and lignin fiber to the first mixture, stir evenly to obtain the second mixture; wherein, the particle size of the TiO2-loaded activated carbon composite particles matches the particle size of the gypsum particles to form a dense filler. S3: Lay the first basalt fiber felt 21 and the first dense fiber bundle preset layer 31 in sequence in the mold, lay the second mixture on the first dense fiber bundle preset layer 31, and then lay the second dense fiber bundle preset layer 32 and the second basalt fiber felt 22 in sequence on the second mixture to form a slab. S4: A porous sound-absorbing layer 40 is formed on the upper surface of the second basalt fiber felt 22. After curing and drying, an integrated home decoration gypsum board is obtained.

[0030] Example Example 1

[0031] Preparation of the first mixture: Add the intumescent flame retardant and nano-silane waterproofing agent to the gypsum slurry and stir evenly to obtain the first mixture; Preparation of the second mixture: TiO2-loaded activated carbon composite particles, lightweight high-strength aggregate and lignin fiber are added to the first mixture and stirred evenly to obtain the second mixture; wherein the particle size of the activated carbon composite particles matches the particle size of the gypsum particles. Slab forming: The first basalt fiber felt 21 and the first dense fiber bundle preset layer 31 are laid in sequence in the mold. The second mixture is laid on the first dense fiber bundle preset layer 31. Then, the second dense fiber bundle preset layer 32 and the second basalt fiber felt 22 are laid in sequence on the second mixture to form a slab. Sound-absorbing layer and finished product: A porous sound-absorbing layer 40 is formed on the upper surface of the second basalt fiber felt 22. After curing and drying, integrated home decoration gypsum board is obtained.

[0032] (II) Example 2 Preparation of the first mixture: The first mixture was prepared using the same method as in Example 1; Preparation of the second mixture: The second mixture was prepared using the same method as in Example 1; Slab forming: The layers are laid out in the same way as in Example 1 to form a slab, wherein the fiber bundles of the first dense fiber bundle preset layer 31 and the second dense fiber bundle preset layer 32 are arranged along the length direction of the slab; Sound-absorbing layer and finished product: The porous sound-absorbing layer 40 is formed by the same method as in Example 1 to obtain integrated home decoration gypsum board.

[0033] (III) Example 3 Preparation of the first mixture: The first mixture was prepared using the same method as in Example 1; Preparation of the second mixture: The second mixture was prepared by the same method as in Example 1, wherein the particle size of the activated carbon composite particles was smaller than that of the lightweight high-strength aggregate, thus achieving multi-level dense filling. Slab forming: Lay out each layer using the same method as in Example 1 to form a slab; Sound-absorbing layer and finished product: The porous sound-absorbing layer 40 is formed by the same method as in Example 1 to obtain integrated home decoration gypsum board.

[0034] (iv) Comparative Example 1 (all components mixed at once) Preparation of the mixture: The intumescent flame retardant, nano-silane waterproofing agent, TiO2-loaded activated carbon composite particles, lightweight high-strength aggregate, and lignin fiber are all added to the gypsum slurry at one time and stirred evenly to obtain the mixture; Slab forming: Lay out each layer using the same method as in Example 1 to form a slab; Sound-absorbing layer and finished product: A porous sound-absorbing layer 40 is formed using the same method as in Example 1 to obtain a comparative gypsum board.

[0035] (v) Comparative Example 2 (without layered structure) Preparation of the first mixture: The first mixture was prepared using the same method as in Example 1; Preparation of the second mixture: The second mixture was prepared using the same method as in Example 1; Slab forming: Only the second mixture is laid in the mold, without laying the basalt fiber felt and the pre-set layer of dense fiber bundles, to form a slab; Sound-absorbing layer and finished product: A porous sound-absorbing layer 40 is formed on the upper surface of the board blank using the same method as in Example 1, resulting in a comparative gypsum board.

[0036] The gypsum boards in Examples 1-3 exhibit excellent comprehensive performance due to their step-by-step addition sequence and specific layered structure: there is no mutual interference between the functional components, the layered structure is complete and dense, and the boards simultaneously possess eight functions: high water resistance, high fire resistance, high impact resistance, high nail holding power, efficient formaldehyde decomposition, high sound insulation, high crack resistance, and high anti-sagging. All functions work synergistically to enhance each other's performance. Comparative Example 1 (all components mixed at once): Due to the waterproofing agent coating activated carbon and the flame retardant eroding the fiber felt, the formaldehyde purification efficiency and waterproof performance were significantly reduced, and many functions were degraded. Comparative Example 2 (without layered structure) lacks basalt fiber felt and a pre-set layer of dense fiber bundles, resulting in significantly insufficient impact resistance and nail-holding power, failing to meet the requirements of high-quality home decoration.

[0037] The above results demonstrate that this application achieves multifunctional synergistic effects of gypsum board through a step-by-step addition sequence and a specific layered structure design, demonstrating significant technical advantages.

[0038] This application achieves spatial isolation of each functional component during the slurry mixing stage by adding them in a step-by-step sequence, and realizes functional zoning by combining a symmetrical layered structure: Step-by-step addition to eliminate component interference: The first step involves adding an intumescent flame retardant and a nano-silane waterproofing agent, allowing them to preferentially bond and anchor to the gypsum matrix; the second step involves adding TiO2-loaded activated carbon composite particles, lightweight high-strength aggregate, and lignin fibers. The activated carbon composite particles, due to their subsequent addition, maintain their intact porous structure and photocatalytic activity and are not coated by the waterproofing agent; the flame retardant is already anchored in the matrix and does not directly contact the subsequently laid fiber felt, thus avoiding interface erosion.

[0039] The layered structure achieves functional zoning: basalt fiber felt provides impact resistance, the pre-layered dense fiber bundle provides nail holding function, the core layer provides water resistance, fire resistance, formaldehyde purification, crack prevention, and sinking prevention function, and the porous sound-absorbing layer provides sound insulation function. Each functional layer is spatially separated and does not interfere with each other.

[0040] Synergistic effect of dense filling: The particle size of activated carbon composite particles and gypsum particles are matched to fill the gaps in the matrix, simultaneously achieving structural enhancement and retention of formaldehyde purification function, achieving a synergistic effect of "1+1>2".

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
